“Education must be based on the certainty that faults cannot be atoned for or blotted out, but must always have their consequences. At the same time, there is the other certainty that, through progressive evolution, by slow adaptation to the conditions of environment, they may be transformed.”

Swedish writer and social thinker

Ellen Key was a Swedish writer and social thinker associated with the Modern Breakthrough movement. She lived from 1849 to 1926 and wrote on family life, ethics, education, and women's rights. She is especially remembered as an early advocate of child-centered education and parenting. Her work also placed her among the women’s suffrage advocates of her time, and her writing often returned to questions of home, moral life, and how society should shape the next generation.
